COUNTING ATTACHMENT FOR MACHINES.

SPECIFICATION forming part of Letters Patent No. 317,438, dated May 5,1885.

Application filed January 14, 1885. (No model.)

To all whom, it may concern: Be it known that I, ARTHUR M. BURNHAM, ofGardiner, in the county of Kennebec and State of Maine, have invented anew and useful Improvement in Counting-Machines, which improvement isfully set forth in the following specification and accompanyingdrawings, in which- Figure 1 shows the working-parts of invention, whichare inclosed in a box; and Fig. 2

shows the dials and indicators.

Like letters of reference indicate like parts. The object of myinvention is to construct a counting machine which may be readilyattachcd to another machine for the purpose of accurately counting anysmall articles, as i wedges and the like. It is particularly designed tobe attached to machines for making wedges, patented by me April 29,188i,

with other machines to count small articles or to count cakes of ice,&c.

In the drawings, a is a box inclosing the working-parts and having thedials and indi- 2 5 cators thereon.

b is a trough along which the articles to be counted pass. 1 c is an armextending downward into the l trough, the lower end 5, coming near thehot i tom thereof. This arm is secured at 6 to the i spindle d. Theseparts are common to both figures.

In Fig. 1 the spindle d is shown passing inside the box a, and workingin the bearings s s. 5 Upon this spindle is a short arm,f, secured atnearly a right angle with the rod 0. The rod 6 works loosely in thebearings 0 0, and has upon it the spring h, secured thereto at S. Theother end of this spring is a catch, 7. g is a short link, connectingthe arm f to the rod 0 at 10 9. v

j is a wheel, rigid on the spindle 2, and having teeth out in the outeredge.

t is a spring-pawl, which engages the teeth 4 5 on the wheelj and holdsit steady.

7c is a small cog-wheel, also rigid on the spindle 2, and engaging thecog-wheel l, which is rigid on the spindle 3. in is another smallcog-wheel rigid on the spindle 3, and en gaging the cog-wheel n, whichis rigid on the spindle 4. The spindles 2, 3, and 4 project through theface P, and have the indicators as w 00 thereon.

The face P has three dials, t u 10, thereon. The dial 2? is divided intoten (10) spaces, and each of these into ten (10), so that it can be readto units. The indicator a is attached to the spindle 2, w to 3, and a to4. The dials a and 10 are each divided into ten (l0) spaces.

To exclude the dust, the face I may be cov- 6 ered with a glass.

The whole operates as follows: A wedge from the machine passes down thetrough bin the direction indicated by the arrow. It strikes the lowerend of the arm at 5 and swings it far enough to allow the wedge to pass.This turns the spindle d and arm f, this arm being connected by the linkg to the rod 0, the rod 0 is raised, the catch 7, engaging a tooth onthe wheel j, carries that wheel around one notch, where it is held bythe spring-pawl i. As soon as the wedge passes the arm 0, it swings backinto place, the rod 0 drops, and the catch 7 engages the next tooth. Thewheel k is one-tenth the size of l, and m one-tenth the size of a, sothat a indicates hundreds and to thousands.

The rod 0 may be operated in various ways to accomplish the same result,and ordinary dogs worked by springs may be substituted for h and i.

\Vhat I claim as my invention is- 1. In a counting-machine, the arm 0,and spindle 1, having the arm f thereon, in com- ;bination with the rod0 and wheel j, connected and operated by the link 9, spring h, and pawli, as described.

2. In a counting-machine, the arm 0, spindle d with arm f thereon, rod6, and wheel j, all connected and operating as set forth in com- 0bination with suitable indicators for the purposes specified.

In testimony whereof I have in the presence of two witnesses subscribedthe foregoing specification.

ARTHUR M. BURNHAM.
